Winter is set to give Delaware another slap in the face Sunday night into Monday, with up to 6 inches of snow forecast for St. Patrick's Day.

Winter is set to give Delaware another slap in the face Sunday night into Monday, with up to 6 inches of snow forecast for St. Patrick's Day.

The National Weather Service has issued a winter storm watch for Sunday evening through Monday morning for the entire state. The weather service is calling for 3 to 6 inches of snow. The heaviest snowfall is predicted for Kent County and eastern Sussex County.

And forecasters say this may not be the season's last close encounter of the shovel-and-salt kind.

"Hopefully, this is the last one that will be a road issue, because the timing is overnight, so it's going to stick a lot more easily than if the bulk of the storm were during the day," meteorologist Anthony Gigi said.

And after such an erratic winter he said not to rule out the possibility of snow even in April, which he called "infrequent but not unprecedented."

For the coming snow, the Department of Transportation is monitoring forecasts to set a roll-out plan, said spokesman Jim Westhoff.

"Our salt stockpiles are good, we made whatever fixes we need to the equipment and we're ready to go," he said.

After another taste of spring with a balmy Saturday, things turn for the worse later in the weekend.

National Weather Service forecasters say Delaware will sink into a chill Sunday with a a coastal low-pressure front due to deliver "wintry precipitation" as the weekend ends.

The forecast is bad enough to warrant the service posting a "Hazardous Weather Outlook" statewide through Monday.

After statewide highs expected to get near or top 60 on Saturday, but the temperature will fall precipitously – along with springtime spirits – with Sunday highs in the low 40s.

Rain is due to shift to snow by midnight. The heaviest snow should fall overnight and start tapering off Monday morning before ending completely Monday afternoon. The temperature overnight will dip into the 20s but will seem colder with blustery winds hitting 10 to 20 mph, with gusts between 30-40 mph.
